1865299 - Artifact builds can't find artifacts when git-cinnabar knows of local commits unknown to mozilla-central/autoland

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Mike Hommey [:glandium]]

It fails with this message:

Exception: Could not find any candidate pushheads in the last 50 revisions.
Search started with e664fbc3ec002ca7497b35362146728122477413, which must be known to Mozilla automation.

e664fbc3ec002ca7497b35362146728122477413 is a changeset unknown to Mozilla automation, but its parent is known. It comes from some fancy stuff I did locally, but it could just as well come from git cinnabar fetch'ing from try, which would be a more common way to end up in this situation.

Attachment: Bug 1865299 - Try harder to find candidate pushheads.

_get_recent_public_revisions is not reliably giving us revisions that
are available on the trees that artifacts are taken from. With both
mercurial and git, it is possible to end up in a situation where the
first few entries are only available on some private branch (but still
"public" in mercurial's or git-cinnabar's eye).

In that case, try parent revisions.
